text buttons

Hello, can somebody please tell me how to fix the buttons for editing text?

Instead of being displayed like these nice little white cubes above the text field, they look like big red stacked bars with a single letter (B / I / Link etc.) in each bar, so it’s basically one big red block. Also the “notify me” square is not located where it’s supposed to be. :/ The buttons do work, but they look weird. I’m using WooCommerce, WPML, BuddyPress and bbPress.
